To all whom #may concern: Y 1

Be it known' that I, FRANK W. Ansrr, a citizenof the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in a Suspension rI ire,of which the following is a specifica'tion.

Une object of my invention is to provide a suspension form of support for an outer casing of a tire for an automobile or the like.

Another object of my invention is to provide improved supports for anti-friction members on which the weight carried by the tire may be supported by a cab-le passing round the interior of the tire.

Another object is to provide interlocking plates joined to a flexible liner, a portion of which carry part ofthe anti-friction members.

Another object is to provide means foi` positively spreading the tire sideways'when un extra weight or stress is thrown thereon.

With these and incidental objects in view`| the invention consists of certain novel features of construction and combination of parts, the essential elements of'which are hereinafter described with reference to the drawings which accompany and form a part of this specication. f

In the drawings, Figure 1 is a longitudinal sectional View of a portion of a tire, 'emiv bodying my invention; Figure 2 is a transu verse section taken on the line 2 2, Figure 1; Figure 8 is a transverse section taken on the line 3--3, Figure 1; Figure 4 is a transn verse section taken on the line 4 4, Figure 1; Figure 5 is a section similar to that shown in Figure 1, but showing the manner in which the cable is tightened; Figure 6 is an enlarged sectional detail showing the bolt used in tightening the cable; and Figure 7 is a side elevation of a fraction yof the liner, showing the interlocking plates riveted thereto. Y

As shown in Figures 1, 2, and 3, the rim 1 carries therearound a canvas strip 2, which.,

" be built up in any1. suitable manner and has riveted thereto multiple U-shaped supports 3, in which are journalled pulleys 4.`

juxtaposition with plates 7 which are likewise carried bythe fiexiloleiliner 5, and these' plates t have scallopedy edges, l,as 'plainly shownin Figure 7; M The edges of the plates are turned over as at 8, Figure 2, to stiften ,the plates and also to vprevent any sharp edges coming in contact -with the flexible gliner.

Riveted to the plates 6 are supports 9, carrying journalled therein pulleys 10,`and supported by the hinged. links 11 aremultiple oating supports 12, carrying jourfl nalled therein pulleys 13.

The cable 14 passes about the interior of the tire and, passing under the multiple pulleys 10 and over the multiple pulleys 4, as viewed in Figurel, supports the outer portion of the tire onthe inner portion of the 'tire by the lineal strength ofthe cable.

Positioned between adjacent pulleys 10 the pulleys 13 take a certain amount of thrust from the cable and through the hinged links 11 tendto spread the plates 7 so as to assist in establishing the resiliency of the tire.

Looking at Figure 5'it'will be seen thaty the felly 15 has a guard plate 16 positioned thereover and an aperture is provided through the felly for bringin'g the ends 17 and 18 of the cable therethrough.

Support 26, mounted on the rim 1, carries grooved drums 28 and 29, respectively, over which the ends of the cable 14 may be easily drawn.

, A lock bolt 19 .isadapted to receive the two ends 17 and 18 of the cable with a wedge 2O between the two ends, and when the nut 21 is turned toward the split end of the bolt the cable ends are securely gripped by the corrugated vsurfaces of the bolt. l

`With the lock bolt positioned inthe aper ture as shown in Figure 5, a washer 22'is placed thereover and nut 23 is provided for drawing the bolt 19 outwardly from the felly, thereby stretching the cable 14 as taut as desired.

A lock nut 24is provided to prevent the nut 23 from loosening in use.

The exible liner 5 is supported by a. carcass or outer casing 25, Figure 2, which may not wish it understood that I limit myself to this construction, as it is evident that the application of the invention may be varied in many ways within the scope of the following claims.

Claims:

1.. In a suspension tire the combination with a` hollow carcass, of a cable positioned concentric therewith and within the hollow thereof, anti-friction supports positioned eX- teriorly of said cable and supporting the tread portion of said carcass, vanti-friction members positioned within said Vcable and supported by the side walls of said carcass, whereby pressure exerted on the tread of said carcass may be transmitted through said cable to the side walls of said carcass.

2. In a suspension tire the combination with a hollow carcass, of a iexible liner, multiple side plates riveted to said liner, multiple tread plates riveted to said liner, said side plates and said `tread plates having their edges scalloped and the tabs thereof in close juxtaposition one to another, without contact therebetween, and means including a cablegan'd anti-friction supports for said cable for transmitting pressure fromV said tread plates to said side plates.
